Paste the data into a spreadsheet program and create a graph with temperature on the x-axis and volume on the y-axis. Also create a graph for the data labeled Real Gas N2.

Using the spreadsheet program, fit the ideal gas data to a line or printout the graph and use a ruler to draw the best line through the data. The lowest possible temperature is reached when an ideal gas has zero volume. This temperature is the x-intercept for the plotted line.

Q: What is this temperature?

Q: Now do the same analysis with the real gas data (N2). What temperature did you find?
